I am renovating a small home and the one item I cannot seem to find room for is the hot water heater. (Ok, I do have some alternatives but...) I have surfed the internet and found waterheaters that can be installed outdoors (in mild climates), tankless systems which need less space, point-of-delivery systems with under sink mounting, hanging horizontal heaters (although this one looks commercial). After renovation my home will have: 1 Jacuzzi type tub, 1 regular tub, 2 showers, 3 bathroom sinks, 1 kitchen sink, 1 dishwasher, 1 washing machine. I am also conidering radiant floor heating in the kitchen/family room but of course this is just another hot water demand item. What do I use??? One of the above, a combination of some of the above??? ANY HELP WOULD BE APPRECIATED! Also, note that while I won't say cost is no object, I will spend more to get a good efficient system that can handle the hot water needs without the infuriating running out of hot water.
